How much soil goes down the drain -- New data on soil lost due to water

EurekAlert! - Jue, 12/14/2017 - 23:00
According to a new study, almost 36 billion tons of soil is lost every year due to water, and deforestation and other changes in land use make the problem worse. The study also offers ideas on how agriculture can change to become a part of the solution from being part of the problem.

EurekAlert! - Jue, 12/14/2017 - 23:00
A new genetic analysis of fungal yeast infections (candidiasis) from around the world has revealed surprising secrets about how these microbes reproduce and cause disease, according to a new study published in Current Biology from researchers at the Centre for Genomic Regulation in Barcelona, Spain.

Quantum memory with record-breaking capacity based on laser-cooled atoms

EurekAlert! - Jue, 12/14/2017 - 23:00
The emerging domain of parallelized quantum information processing opens up new possibilities for precise measurements, communication and imaging. Precise control of multiple stored photons allows efficient handling of this subtle information in large amounts. In the Quantum Memories Laboratory at Faculty of Physics, University of Warsaw a group of laser-cooled atoms has been used as a memory which can store simultaneously up to 665 quantum states of light. The experimental results have been published in a prestigious Nature Communications journal.

Extending food safety training to other countries could save live

EurekAlert! - Jue, 12/14/2017 - 23:00
Food safety practices that Americans take for granted -- washing hands with soap, refrigeration, and not cutting raw meat and vegetables on the same surface without disinfection -- are not widely practiced in other places around the world, and researchers in Penn State's College of Agricultural Sciences want to change that.

New chronic kidney disease audit published

EurekAlert! - Jue, 12/14/2017 - 23:00
Sustainability and Transformation Partnerships, Clinical Commissioning Groups and primary care practices must all work together to improve outcomes for patients with Chronic Kidney Disease (CKD), according to the national Chronic Kidney Disease Audit published today. The Audit was commissioned by the Healthcare Quality Improvement Partnership (HQIP) and conducted by the Informatica Systems, the London School of Hygiene & Tropical Medicine, UCL (University College London) and Queen Mary University of London.

Vitamin deficiency in later life

EurekAlert! - Jue, 12/14/2017 - 23:00
One in two persons aged 65 and above has suboptimal levels of vitamin D in the blood. This is the conclusion of an investigation conducted by researchers at the Helmholtz Zentrum München, as part of the population-based KORA-Age study in the region of Augsburg. Moreover, as the authors of the study report in the peer-reviewed journal Nutrients, one in four older adults has suboptimal vitamin B12 levels.

Health and spirituality values influence attendance for pelvic-floor dysfunction treatment

EurekAlert! - Jue, 12/14/2017 - 23:00
New research from psychologists and health professionals in Swansea has found that the types of life values that patients hold affect their attendance at medical treatment for pelvic-floor dysfunction, a condition affecting over 25 percent of all women in the UK.

Real-time observation of collective quantum modes

EurekAlert! - Jue, 12/14/2017 - 23:00
When symmetries in quantum systems are spontaneously broken, the collective excitation modes change in characteristic ways. Researchers at ETH have now directly observed such Goldstone and Higgs modes for the first time.

Distinct human mutations can alter the effect of medicine

EurekAlert! - Jue, 12/14/2017 - 23:00
About one third of all medicine binds to the same type of receptor in the human body. An estimated 3 percent of the population have receptors of this type that are so genetically different that they are predisposed to altered, ineffective or adverse responses to medicine, a new study from the University of Copenhagen and the MRC Laboratory of Molecular Biology in Cambridge shows.

The hazards of antibiotic resistances remain high

EurekAlert! - Jue, 12/14/2017 - 23:00
According to a survey among researchers, it is difficult to quantify the true extent of the hazards of antibiotic resistances to humankind. The survey conducted by Freie Universität Berlin and Karlsruhe Institute of Technology (KIT) will be introduced on the occasion of the international World Antibiotic Awareness Week on Sunday, Nov. 19. It reveals that among researchers worldwide, there is broad agreement on the fact that antibiotic resistances are serious health hazards. The number of related deaths, however, cannot be determined reliably.
